我正在嘗試獲取部署后 Flask_ngrok 或 py-ngrok 生成的域名或 IP 地址。我想將flask_app部署到本地主機并在主頁上獲取新的IP地址或域名。IE：如果我訪問127.0.0.1/我希望它返回類似的內容 You can now log in through https://aaf8447ee878.ngrok.io/我嘗試檢查目錄并閱讀一些幫助，但我仍然無法得到它。預先感謝?

不要在name == ' main '之前導入flask_ngrok添加此函數
def ngrok_url():
global tunnel_url
while True:
try:
print(ngrok_address)
except Exception as e:
print(e)
并在 app.run() 之前放置
thread = Timer(1, ngrok_url)
thread.setDaemon(True)
thread.start()
并運行警告：如果您不希望在 ngrok url 函數中將 print 替換為您想要對 url 執(zhí)行的任何操作，這將使您的代碼編輯器/或終端崩潰

我發(fā)現最簡單的方法是在用戶訪問該網站時復制網址。你可以通過...來做到這一點
@app.before_request
def before_request():
global url
url = request.url
# url = url.replace('http://', 'https://', 1)
url = url.split('.ngrok.io')[0]
url += '.ngrok.io'

你不需要那個
global tunnel_url
def ngrok_url():
while True:
try:
print(ngrok_address)
except Exception as e:
print(e)
您也可以在導入集之后 刪除name == ' main '之前的線程部分ngrok_address = '' ，然后您可以在代碼中的任何位置訪問 ngrok_address
